Recently, the "antigen detection" of COVID-19 has been the focus of people’s attention. As a key guarantee enterprise for national epidemic prevention and control, Dawn Polymer acted quickly and worked overtime for several days to develop and produce products related to antigen detection kits to ensure that orders would be delivered on time. "The needs of the society are the direction of our efforts." Wu Di, the company's deputy general manager, said, "many customers have used it in batches, and the market feedback is good."

On March 11th, The State Council's Comprehensive Team of the Joint Prevention and Control Mechanism for the COVID-19 decided to add antigen testing as a supplement to nucleic acid testing. Subsequently, all provinces temporarily included antigen testing reagents and corresponding testing items into the basic medical insurance. Wang Hong, R&D director of Dawn Polymer, said that the company set up an R&D team for the first time, and they worked overtime to complete the experiment on the same day. After many times of processing improvements, the product index requirements were met. Antigens are like the "clothes" on the outside of the virus, and nucleic acids are the genes inside the virus. Antigen testing is to start from antibodies to test "the antigens" to make the virus exposed. It is understood that the antigen detection kit is mainly composed of sampling cotton swabs, extraction tubes, and detection kits. Residents can collect anterior nasal swabs or nasopharyngeal swab samples at home according to the instructions of the product instructions, and the results can be viewed in 15-20 minutes.

"For sampling cotton swabs, the HIPS-S295S we developed has the characteristics of easy molding, easy bending, and high strength." Director Wang Hong said, as a household extraction tube, it is injection molded with PE, which exhibits good transparency, good flexibility, excellent biosafety, and great chemical resistance.

The most important part of antigen detection is to drop the mixture in the extraction tube into the detection kits. "We recommend customers to use HIPS-S295S and ABS-245S reagent kit special materials because with high molding fluidity, it can shorten the molding cycle, improve the production efficiency and agility, and provide customized colors according to customer needs." Director Wang Hong said.

Since the COVID-19 outbroke, Dawn Group, the controlling shareholder of Dawn Polymer, has opened the "melt-blown PP material-melt-blown fabric-mask" industrial chain, which has contributed to the prevention and control of the epidemic at home and abroad. “The R&D, production, and application of antigen detection kit-related products are not only a concrete manifestation of extending the medical and health industrial chain, but also an important measure to help normalize the epidemic prevention. " Tian Hongchi, a national key talent engineering expert and general manager of Dawn Polymer, said that in the future, they would adhere to the business philosophy of "products-rooted, people-oriented, technology-led, and customers-first" to ensure the production needs of anti-epidemic materials and protect people’s health and safety.
